Grand Sport Extra vs High Roller II review

Features

• PureGrip Compound

  The advanced new compound

  Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable – both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia).

• NyTechBreaker

  Nylon fabric in the performance sector

  Our new NyTech Puncture Protection has been developed based on the proven Continental SafetySystem Breaker. Its nylon fabric makes it resistant to punctures and cuts like Kevlar reinforced high strength fibres, but offers lower rolling resistance and reduced weight. The NyTech breaker sits between the SafetySystem and the PolyX Breaker® as a more effective puncture protection casing in the performance sector.

• 3C MaxxTerra An intermediate compound configuration used in select mountain tires. 3C MaxxTerra is softer and offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than MaxxGrip.

• 3C MaxxGrip 3C MaxxGrip uses the softest rubber compounds to offer the ultimate in grip and slow rebound properties for unparalleled traction in downhill applications.

• Wide Trail Wide Trail (WT) construction optimizes the tire’s tread layout and profile on today’s modern, wider rims. Traditional tires are designed around older, narrower rims and can create an overly square tire profile, leading to less than optimal performance. WT tires are optimized for a 35mm inner rim width but are proven to work over a range from 30-35mm inner rim widths, depending on the rider’s preference. Maxxis Wide Trail XC tires are optimized for use with 30mm internal width rims, but they will perform well on rims as narrow as 25mm. Maxxis does not recommend rims wider than 30mm or narrower than 25mm

• Tubeless Ready Tubeless tires provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tire; and less chance of flatting because there is no tube. Liquid sealants should only be used in the following types of tires: tubeless road, tubular, and tubeless ready. The use of liquid sealants in any other Maxxis tire will void the warranty.

• EXO An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tires. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.

• Downhill (DH) Two layers of casing material are used from bead to bead, providing additional protection and sidewall stiffness for downhill applications.

• Double Down (DD) DoubleDown (DD) is the next step in the evolution of the dual-ply tire casing for enduro racing. Two 120 TPI casing layers reinforced with a butyl insert provide the enduro racer with the support and protection of a downhill tire, but in a lighter package.
